Bastille Day attacker was bisexual, had fling with elderly male retiree

France’s truck terrorist had romantic flings with both men and women, with his main male squeeze being a 73-year-old retiree, investigators have revealed.

French police officers discovered lurid photos of Mohamed Lahouaiej Bouhlel’s bisexual encounters on his mobile phone after they shot him dead in the cab of the truck he used to run over and kill 85 people and injure scores more on Nice’s Promenade des Anglais last Friday.

The fitness fanatic and divorced father of three was a regular on dating sites, hooking up with male and female lovers, while his “principle lover” was a 73-year-old man whose identity has not been released, according to multiple reports.

Bouhlel’s phone is chock full of racy messages, videos and photographs, including some that show him sleeping with his sexual conquests.
